IMPRovEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 131,086, datedSeptember 3, 1872.

Specification describingh certain Improvements in Burners, invented byMICHAEL B. DYOTT, of the city of Philadelphia, in the State ofPennsylvania.

kThe rst part of my invention relates to the construction andarrangement in the supplypipe, immediately belowr the generator, of acore of porous metallic packing of wire or wiregauze, surrounded orlapped tightly around by muslin or other poor heat-conducting fabric,and inserted rmly in the said part of the pipe, so'V as to serve as anincombustible retarder therein, and at the same time be prevented by thelapping fabric from becoming y unduly heated by the inclosing orsurrounding pipe. The second part of my invention relates to theconstruction of the openin gthrou gh the plug of the stop-cock in adirection oblique in relation to the supply and discharge openings inthe vertical pipe below the generator and burner-head, for the purposeof more eiectuallypreventin g any leaking through the said openings whenthe plug is shut consequent upon the ridges which are produced aroundthe plug and barrel by wear.

Figure l is a vertical central section`of the vapor-burner embodying myinvention. Fig. 2 is a modification of the stop-cock, shown in Fig. 1.

The head A ofthe burner is a hollow retort perforated with a ring ofholes, a', near its lower end. The heater B is screwed into the upperend of the hollow head A, and projects downward, as an inverted cone, toor into the upper end of a hollow mixer, (l, through which mingledvaporand air rise. The vapor passes up into the mixer C through a generatoror narrow hole, d', made in the upper end of the supply-pipe D, whilethe atmospheric air enters C through a ring of holes, o', at a point alittle above the vapor-hole d', and thus the vapor and air mingledtogether impinge against the surface of the heater B, and nally escapethrough the ring of jet-holes a', which, being ignited, heat and keepheated both the head A and heater B. The reiiector F is screwed fastupon the upper end of the burner-head A, or to that of the heater B, andis curved on its under side so as to reiiect downward and outward thelight of the ignited jets, which radiate from the ring of holes a belowit, the

said jets of flame in radiating from the ring of holes a curving upwardtoward the reflector F, as indicated by the arrows in Fig. 1. Abell-shaped guard or fender, H, is fixed around the outside of the mixerC, so as to project a little below the ring of air-holes cand thus forman annular. guard for the purpose of protecting the said holes c fromsudden drafts or gusts of wind, substantially as described and shown, inthe patent granted to me July 4,1871.

The core of metallic packing E consists, in the present case, of abundle of ne wire cut in lengths to correspond with the length of thechamber of pipe D, and lapped tightly around with muslin e', so astoform a compact cylinder fitting the said pipe D. When the stop-cock Gis opened the fluid from below rises and lters through the porousmetallic core E, while the lapping of muslin e prevents the warmth ofpipe D from being transmitted to the core, and the uid passing throughthe narrow hole d becomes heated, volatilized, and mingled withatmospheric air in C, and iinally escapes in dames from the jet-holes ain the headA. The lower end of the mixing-chamber or pipe O and theupper end of the core-pipe D are connected together by a Iiange on eachwith an isolating layer of cork, d, or other poor conductor of heatbetween, so as to prevent the chamber C from heating the contents inpipe I). The barrel g of the stop-cook G is cast obliquely across thesupply-pipe below D, and the hole 3 through the plug g is madecorrespondingly oblique, so that when the cock is open the said hole 3in the plug g aligns with the bore 4, and allows the fluid to passfreely upward through the core E; but, if the plug be now turned halfaround the hole 3 in the same will come into the position indi- 'catedby the dotted line c o, and effectually prevent any leaking of the iiuidthrough the cock. It will be readily seen that the Obliquity oftheposition of the cock G will afford ready access for operating the plug gby means of a wrench, when the cock is above reach by hand, as instreet-lanterns. Fig. 2 is a modification of the cock, with a plughaving an oblique hole, when the latter is applied in a barrel at rightangles to the supply-pipe, the bore 4 of the supply-pipe be ing obliquedboth above and below the plug so that the parts will operate togetherprecisely as in ,the cock in Fig. 1. In Fig. 1 the plug ot' the cock isa cylindrical screw, and therefore retained in the barrel Without anycollar. 1n Fig. 2 the plug is tapered, and retained in the barrel by acollar, in the usual manner. The burner-head A and the reector F areboth in this instance made of iron, and coated ou the outer surfacesWith nickel and then burnished, thus producing a brilliant reiiectingsurface that will not be impaired by the flames. The head A andreflector F may be made of White porcelain, for the same purpose.

I claim as my invention- 1. The incombustible porous core E, lappedaround With muslin or other poor conductor of heat, and inserted Withinthe pipe D, the saidA across the saine, as shown in Fig. 1. Y
